SCCER BIOSWEET Annual Conference 2019

The 6th Biomass for Swiss Energy Future Conference was held at HSLU in Horw on September 3, 2019. Approximately 80 attendees listened to nine presentations, studied the 35 posters along the most relevant biomass value chains in Switzerland, and networked with members of the biomass energy research community and with technology application partners. This year‘s event focused on producing…

Modelling and validation of biomass combustion in a screw burner

A combined 1D-fuel-bed and 3D-CFD model for the simulation of an innovative 35 kW screw burner has been developed and validated with experiments. The 1D-fuel-bed model is a further development of a previously presented walking column approach and accounts for the special transport conditions in a screw burner. A new reduced chemical mechanism…

Scale-up methodology for automatic biomass furnaces

This work presents a methodology to perform the scale-up of a solid fuel furnace to a higher heat output with maintaining or improving the burn-out quality. As basis to derive the scale-up concept, an example of a 35 kW screw burner for biomass fuels is investigated. Based on the Pi-theorem, the relevant dimensionless parameters are derived and similarity rules for the…

A combined hydrothermal gasification – solid oxide fuel cell system

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system operating without external connection to sewer pipes was used as a feedstock for HTG process. The leachate effluent was characterized…
